I have a friend who used her new Samsonite Sahora Brights luggage on a cruise and when she got it back it had dirt marks on it and scuff marks on the hard plastic part. I was thinking of spraying mine with upholstry Scotchgard before I use mine. Is there also a cleaner she can use to clean her material part of the luggage? To let you know the Sahora Brights are very bright light greens and pinks etc. I know no matter what, our luggage gets abused but maybe we can protect it before traveling so they don't look awful after a use or two. Any suggestions sure would be appreciated!
